MACHINE FOR CLEANING OR SCOURING WHEAT.

SPECIFICATION forming part of Letters Patent No. 359,867, dated March 22, 1887.

Application filed Angust ll, 1886. Serial No. 211,137. (No model.)

To all whom, it may concern:

Be it known that I, Annnns EMIL J ERNAN- DER, a resident of Rochester, in the county of Olmsted and State of Minnesota, have invented certain new and useful Improvements in Machines for Cleaning or scouring Vheat; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side view of my improved wheat cleaning or scouring machine. Fig. 2 is an end view of the same. Fig. 3 is a longitudinal vertical sectional View of the machine, and Fig. 4: is a vertical crosssection.

Similar letters of reference indicate corre sponding parts in all the figures.

My invention has relation to the class of machines for cleaning or scouring wheat, and which are also adapted for hulling or scouring other grain, in which heaters having radiating arms revolve within perforated cylinders revolving in the opposite directions to said heaters; and it consists in the improved construc tion and combination of parts, as will behereinafter more fully set forth and claimed.

In the accompanying drawings, the letter A indicates a rectangular frame, having bearings B B in its end pieces, in which bearings a horizontal square beater-shaft provided with journals C revolves, said shaft having a bandpulley, 1),,01 similar gear at one end and a pinion, E, secured upon its other end. The square beatershaft has a number of beaterarms, F, secured upon it, the said beater-arms having square perforations at their middles, by which they are secured upon the shalt, be ing alternately secured at right angles to each other.

The cylinder G has sleeves H H at the centers of its heads. Said sleeves project outward and arejournaled in bearings upon the cross-pieces I inside of the bearings for the beater-shaft. The entire surface of the cylinder is formed with long perforations J, the edges of which project inwardly and assist in abrading the hulls of the grain, while the broken hulls, dust, and other impurities will pass out through the perforations.

The head of the cylinder is provided at the feed end with an internally-cogged flange or rim, L, which is engaged by a pinion, M, upon the inner end of a counter-shaft, N, having a cog-wheel, O,.meshing with the pinion upon the beater-shaft, so that the cylinderniay be revolved slowly in a direction opposite to the direction in which the beatershaft revolves.

The cylinder is surrounded by a casing, P, one end of which is provided with a feed-chute, Q, the lower end of which passes into the cylinder through the sleeve at its end, admitting of grain being fed into the cylinder. A blast fan, R, is attached to the casingfor forcing a current of air into the cylinder and driving out through its sides the hulls, dust, and other impurities, which will fallinto a hopper, S, forming a part of the casing surrounding the cylinder and extendinghearly its entire length; or they may be drawn out by an exhaust-fan.

The discharge end or head of the cylinder is provided with a number of apertures, T, formed with sliding doors U, and the cleaned and scoured wheat or hulled grain is discharged through these apertures, the doors being withdrawn until all the wheat or grain has passed out, whereupon they are again closed, and the discharged wheat or grain falls into a spout, V, secured under the discharge end of the cylinder.

It will be seen that when wheat or grain is fed into the cylinder and it is revolved, the beatershaft revolving with a considerably greater speed and in an opposite direction within it, thewheat or grain will be beaten and scoured by the heater-arms and forced violently against the perforated sides of the cylinder, and that the hulls and otl'lerimpurities will be rubbed off the grain, and that the current of airwhich passes through the cylinder will force the bulls and impurities out through the perforations, while the whole grain will pass out by the dischurge-apertures when the latter are opened.

The, beater-arms are removable from the shaft, so that if they should become either worn out or otherwise damaged they may be removed and new ones put in their places, the

arms fitting freely upon the shaft by means of their central perforations.

If the edges at one side of the arms become Worn out, the arms may be reversed upon the shaft. bringing the other sides of the arms to face in the direction of the revolution of the shaft, so -that the arms will present flat faces with sharp edges, instead of rounded sides, which would be apt to pass too easily through the grain without scouring 0r hulling it.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States-- In amachine for cleaning or scouring wheat, the combination of a frame having a crosspieee at each end within the ends of the frame, a perforated cylinder journalcd in bearings upon said cross-pieces and having its heads provided withsleeves, the discharge-head be as described, for rotating said shaft and cylino der inopposite directions.

In testimony that Iclaini the foregoing as my own I have hereunto affixed mysignature in presence of two witnesses.
